1. Introduction

Singapore has a scarcity in resources, meaning the country has to rely on others while trying to build a sustainable living for ourselves. We regularly import products from other countries, such as fresh food, with an increasing trend (Agri-Food & Veterinarian Authority of Singapore, 2012). We too, also import water from Malaysia, under two bilateral agreements. Singapore is now into its second agreement, which expires in 2061 (PUB, 2013). Singapore also has its method of conducting a sustainable living, such as setting up catchment areas for collecting rainwater. Singapore has a total of 17 reservoirs for the purpose of collecting rainwater (PUB, 2012). Rainwater is collected through an extensive network of drains, canals, rivers, storm-water collection ponds and reservoirs before it is treated for daily and safe consumption (PUB 2013).

We would like to ensure that such sources of water would be able to be purified with low costs, meaning the water beforehand is of acceptable limits. Hence, our project would be about investigating the water quality of Sungei Ulu Pandan River. It is the only river in Singapore that is not dammed up and flows backwards. We would research into the 9 water parameters: Temperature, pH value, dissolved oxygen, biochemical oxygen demand, nitrates, fecal coliform, phosphates, turbidity and total suspended solids. With these 9 water parameters, we would be able to find out the grade for the water quality of the sampled area. We can then analyse, whether it is feasible to purify the water of the river.
